Frequently Asked Questions
Why does renting sometimes build more wealth than buying? ▼
If monthly rent is significantly lower than total ownership costs, investing the savings plus the down payment into index funds can outpace real estate equity over moderate time horizons.
How much should I budget for home maintenance? ▼
The standard guideline is 1% to 2% of the home's total value annually for routine maintenance, repairs, and capital replacements.
